Physics experiments are hands-on activities that help us understand the laws of nature. By testing ideas and observing results, we can learn about concepts like gravity, motion, and energy. For example, dropping different objects to see which hits the ground first can teach us about acceleration and air resistance. These experiments can be simple, like using a pendulum to explore periodic motion, or more complex, like building a circuit to study electricity. Each experiment provides valuable insights and encourages curiosity, making physics an exciting subject to explore in both classrooms and at home.
